Core Features

Stable Operation with Four-Cylinder Design

Equipped with a four-cylinder piston structure, the compressor ensures balanced load distribution, minimizing mechanical vibration and enabling long-term continuous operation. The 50 mm bore and 39.3 mm stroke design guarantees consistent refrigerant output, even under demanding industrial conditions.

Energy-Efficient Performance

Optimized for energy savings, the compressor features impact-resistant spring steel valves to reduce airflow leakage and minimized deadpoint clearance for enhanced compression efficiency. Its 5 HP (3.7 kW) high-load motor maintains peak performance while cutting energy consumption, making it an eco-friendly choice for industrial facilities.

Durable & Low-Maintenance Construction

Built with low-friction piston rods, chrome-plated rings, and surface-hardened crankshafts, the BTF4FC-3 .3Z~BTF4CC-9 .3G resists wear and tear for an extended service life. The forced lubrication system and large oil pump ensure continuous oil supply, reducing maintenance frequency and operational costs.

Low Vibration & Noise

The precision-engineered components and balanced multi-cylinder layout significantly reduce operational noise and vibration, creating a quieter working environment for industrial settings.

Comprehensive Protection Mechanisms

Integrated motor temperature protection and discharge temperature protection prevent overheating and system failures. Pressure sensors trigger automatic shutdowns during abnormal conditions, safeguarding both the compressor and connected refrigeration systems.
